NEET BIOLOGY

Detailed explanation-1: -Analogous organs are those organs that have some superficial resemblance, perform similar functions and yet, have different evolutionary origins and hence, different anatomical structures. Homologous organs are organs which have similar functions but different origins.

Detailed explanation-2: -Analogous structures have different morphology, which means they are different in structure but have similar function. Let’s take our bat wing again, and this time compare it to a butterfly wing and a bird wing.

Detailed explanation-3: -Analogous structures are features of different species that are similar in function but not necessarily in structure and which do not derive from a common ancestral feature (compare to homologous structures) and which evolved in response to a similar environmental challenge.

Detailed explanation-4: -They have a different ancestral origin and hence do not have a shared common ancestor. Examples of analogous organs are wings of birds and butterflies, flippers of Penguins and Dolphins, eyes of the octopus and of mammals, sweet potato and potato.
